Chapter 2: Define the Terms

1) Bit : A small unit in computer that is presented by binary digit 0s and 1s. 

• Example: 1 or 0.

2) Byte : It is a group of  8 bits together, which became "a byte". 

• Example: 10110001 (8 bits) = 1 byte.

3) Binary : It  is numerical notation of  "base 2" in computer science. 

    Bit and Bytes are Binary numbers, so it uses only 1 or 0.

• Example: 1011001. 

4) Denary/Decimal : It is the numerical notation of  "base 10" in computer science/coding.

• Example: 914 in base 10 ---> 9*10^2 + 1*10^1 +4*10^0 

6) Hexadecimal : Its  the numerical notation of  "base 16" in computer science/coding.

• Example: 914 in base 12 ---> 9*12^2 +1*12^1 +4*12^0
